I think that the "domminant" variant is to common and sub does not appear enough, also how the hereditary traits works? take priority the impregnator?, the impregnated? or is mixed/random between both parents?
It’s a simplified and stylized model based on real genetics, where each goblin has a genome made of pairs of genes. Each parent contributes one gene from each pair, chosen at random, to their child. If the parents don’t have the same genome lengths, the child gets “Null Genes” in the leftover slots.
After the genes are contributed, the child goes through random mutations. For each gene pair, there’s a 1% chance it will be duplicated or deleted. For each individual gene, there’s a 1% chance it will become a different type of gene at random.
Each type of gene adds a bonus to a particular stat.
Regarding dominance/submission, dominance is the default, and you have to breed for the submissive gene. However, it’s very hard to breed for because of natural evolutionary pressure. A submissive goblin gets topped a lot by other goblins, so she’s always sexually satisfied, and so she’s never in the mood to go impregnate other goblins. Not an efficient reproductive strategy.
The next version of the game (in two weeks, after the jam ratings are over) will mitigate this by making it so goblins you mark with “encourage breeding” will refuse to be topped if they’re already pregnant.
